Example:

Replace ASCII character 173 (inverted exclamation point) with the two- sixteenth note. There are 9 bytes per entry, and entry 0 of the draft table starts at x8011.

9 x 173 = 1557 = x615 (the offset into the table)

x615 + x8011 = x8626 (offset + character 0 lookup table address)

The address for the new lookup table entry for ASCII character 173 is x8626.

Downloading the Lookup Table Data

Use the following example to send the lookup table information to the printer:
